Fuel Vapour System - Got it working!!

[plasmastudent77]

Hi All,

Well I got my 5.5 HP Honda motor running on vapour.

I had to start it on carby, but then switch the fuel off and let the fumes take over.

Construction - its a large coffee tin with 32 mm PVC pipe running into it. The tin lid ( which is an air tight seal on the can ) has 8 holes drilled in it and each hole is 12mm diameter. The 8 black tubes are just 12 mm ( 1/2 inch ) home garden irrigation pipe and it all held together with wet area silicon sealant ( i.e used in bathrooms ). 

Running - I start ion carby, then once the engine warms up, switch off the fuel and let the fumes take over. The tin is approx 6 inches diameter and about 6 inches tall,. I half fill it with petrol, then make sure the 12mm tubes and the 32 mm pipe supplying the carb are close ( 10mm ) but not actually touching the fuel surface in the tin.

I ran it for a half an hour and used very little fuel. Its a rough prototype but works OK and the engine runs with an even note and smoothly. The only thing I dont know about is water injection to compensate for the leaned out fuel mix which means the exhaust valves need water to cool them instead being coole dby unburnt fuel. Engines are designed to waste fuel ( unburnt fuel )  which splashes onto the exhaust valves ot keep them cool.

Feel free to ask questions.

Possibly that is the system , that was invented before 130 years.
I have read (2003) that first an Water-Engine was working.
But this construction was the reconstruct to  mineraloil fuel.


It is to understand that that WAS an better way to let running also the money ..

Have sombody an copy of this ?

Well the set up is really half way between normal carburettor and GEET, but yes youare right, 130 years ago people had these systems. My next step is to try it on a car.

In some ways, we can get rid of fuel injection on cars and use this simple system. I'm hoping to try ( like GEET ) with other fuels as well, maybe even a water/fuel mix.

I dont know how it would go in very cold climates, but I think it would need a normal carburettor to make sure it was a rich fuel mix for cold starting then run on vapours.....

I'm hoping to do some fuel consumption tests for vapour vs non-vapour and post back the results.

Hello plasmastudent77
Thanks for sharing.
I a next step one could test to conect a hose from a electrolyser to the plasticpipe.
It might be of use to cool down the Motor by this way.
keep doing a good job

 If gas is needed to splash back on the valves to keep them cool, how does natural gas and or propane do it? Isn't natural gas and propane a vapor too?
